Supramolecular photodimerization of coumarins.

Supramolecular photocatalysis: insights into cucurbit[8]uril catalyzed photodimerization of 6-methylcoumarin.

Guest induced shape change of the cucurbit[8]uril cavity is likely rate limiting in the supramolecular photocatalytic cycle for CB8 mediated photodimerization of 6-methylcoumarin.

Valine sulfonamidecinnamic acid asymmetric crystal reactions.

Racemic and homochiral valine sulfonamidecinnamic acids crystallize with components aligned by use of the complementary features of hydrogen bonds and molecular topology to give supramolecular dimers. These discrete motifs effectively organize adjacent olefins for UV initiated single-crystal-to-single-crystal [2+2] photodimerization reactions. The racemic crystals produce inversion related cycl...

Coumarin-Containing Polymers for High Density Non-Linear Optical Data Storage.

Optical data storage was performed with various thin polymer films containing coumarin-based derivatives and by using femtosecond laser pulses as well as two-photon absorption processes. Exploring the photodimerization attribute of coumarin derivatives and using appropriate irradiation wavelengths, recording/erasing processes could be carried out in the same area. Second harmonic generation mic...
